74LVC241A
OCTAL BUFFER/LINE DRIVER WITH 3 STATE OUTPUTS
Description
Pin Assignments
The 74LVC241A provides two 4-bit buffers/drivers with separate
output-enable (1OE and 2OE) inputs. When 1OE is low or 2OE is
high, the device passes noninverted data from the A inputs to the
Y outputs. When 1OE is high or 2OE is low, the outputs for the
respective buffers/drivers are in the high-impedance state.

The inputs are tolerant to 5.5V allowing this device to be used in a
mixed voltage environment. The device is fully specified for partial
